Death domain of Ankyrin-3; Death Domain (DD) of the human protein ankyrin-3 (ANK-3) and related proteins. Ankyrins are modular proteins comprising three conserved domains, an N-terminal membrane-binding domain containing ANK repeats, a spectrin-binding domain and a C-terminal DD. ANK-3, also called anykyrin-G (for general or giant), is found in neurons and at least one splice variant has been shown to be essential for propagation of action potentials as a binding partner to neurofascin and voltage-gated sodium channels. It is required for maintaining axo-dendritic polarity, and may be a genetic risk factor associated with bipolar disorder. ANK-3 may also play roles in other cell types. Mutations affecting ANK-3 pathways for Na channel localization are associated with Brugada syndrome, a potentially fatal arrythmia. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN. They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

Death domain of Ankyrin-1; Death Domain (DD) of the human protein ankyrin-1 (ANK-1) and related proteins. Ankyrins are modular proteins comprising three conserved domains, an N-terminal membrane-binding domain containing ANK repeats, a spectrin-binding domain and a C-terminal DD. ANK-1, also called ankyrin-R (for restricted), is found in brain, muscle, and erythrocytes and is thought to function in linking integral membrane proteins to the underlying cytoskeleton. It plays a critical nonredundant role in erythroid development and is associated with hereditary spherocytosis (HS), a common disorder of the red cell membrane. The small alternatively-spliced variant, sANK-1, found in striated muscle and concentrated in the sarcoplasmic reticulum (SR) binds obscurin and titin, which facilitates the anchoring of the network SR to the contractile apparatus. In general, DDs are protein-protein interaction domains found in a variety of domain architectures.

Ankyrins are modular proteins comprising three conserved domains, an N-terminal membrane-binding domain containing ANK repeats, a spectrin-binding domain and a C-terminal DD. ANK-2, also called ankyrin-B (for broadly expressed), is required for proper function of the Na/Ca ion exchanger-1 in cardiomyocytes, and is thought to function in linking integral membrane proteins to the underlying cytoskeleton. Human ANK-2 is associated with "Ankyrin-B syndrome", an atypical arrythmia disorder with risk of sudden cardiac death. It also plays key roles in the brain and striated muscle. Loss of ANK-2 is associated with significant nervous system defects and sarcomere disorganization. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN.

Death Domain: a protein-protein interaction domain; Death Domains (DDs) are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN. Structural analysis of DD-DD complexes show that the domains interact with each other in many different ways. DD-containing proteins serve as adaptors in signaling pathways and they can recruit other proteins into signaling complexes. In mammals, they are prominent components of the programmed cell death (apoptosis) pathway and are found in a number of other signaling pathways. In invertebrates, they are involved in transcriptional regulation of zygotic patterning genes in insect embryogenesis, and are components of the ToII/NF-kappaB pathway, a conserved innate immune pathway in animal cells.

It contains an NT-binding extracellular region that bears four cysteine-rich repeats, a transmembrane domain, and an intracellular DD. p75NTR plays roles in the immune, vascular, and nervous systems, and has been shown to promote cell death or survival, and to induce neurite outgrowth or collapse depending on its ligands and co-receptors. In general, DDs are protein-protein interaction domains found in a variety of domain architectures.

Death Domain of Receptor-Interacting Protein 1; Death domain (DD) found in Receptor-Interacting Protein 1 (RIP1) and related proteins. RIP kinases serve as essential sensors of cellular stress. Vertebrates contain several types containing a homologous N-terminal kinase domain and varying C-terminal domains. RIP1 harbors a C-terminal DD, which binds death receptors (DRs) including TNF receptor 1, Fas, TNF-related apoptosis-inducing ligand receptor 1 (TRAILR1), and TRAILR2. It also interacts with other DD-containing adaptor proteins such as TRADD and FADD. RIP1 plays a crucial role in determining a cell's fate, between survival or death, following exposure to stress signals. It is important in the signaling of NF-kappaB and MAPKs, and it links DR-associated signaling to reactive oxygen species (ROS) production. Abnormal RIP1 function may result in ROS accumulation affecting inflammatory responses, innate immunity, stress responses, and cell survival. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN.
